Resolved! IWDG not stopping on debug when CAN Receive interrupt triggered

I'm having a significant problem debugging my board with CAN traffic. Whenever the debugger is paused, and a CAN message is received via interrupt, the independent watchdog is being reset. As far as I can tell, I'm disabling that peripheral on debug ...

Resolved! Why is ADC + DMA not triggered?

Hi! I'm using STM32 F301C8T for my LLC converter project. I have two MOSFETs switching at variable frequencies ranging from 80kHz to 400 kHz. Due to significant noise caused by switching, I need to time the output voltage measurement between the swit...

Resolved! STM32H743ZIT6 random startup problems when D-Cache enabled

Hello,I am about to improve the execution speed of an existing code base on a NUCLEO-H743ZI2 board.So far, I have the following memory setup:Instruction Memory:ITCM for time-critical functionsFLASH (+ I-Cache) for remaining instructionsData Memory:AX...

Resolved! switch from stm32f407 to H753 PWM period halved

Hi,i had a programm running on the stm32f407 and PWM output via Tim2 The timer is configured with clock 84MHz and PWM Counter Period 5040 which gives me a period time of 60us. The timer is clocked via APB1. this works finenow i use an h753 with the ...

Resolved! we have implemented the serial terminal for stm32u575ziq nucleo board when we config UART with DMA fails to transmit data after some time. But when we use UART with interrupt then it works fine Anyone knows why it is happening like that?

Resolved! Hello ST team, I am trying to create a sample project for STM32H757 microcontroller in VS code IDE using STM code extension but I am unsuccessful in setting up the project and ending up in make file issues, any guidance here would be appreciated.

Resolved! Input capture interrupts not fired on STM32F401

Hello,I have configured a CUBE IDE project to match a Nucleo-F401RE board to measure the system clock pulses (at 84MHz) between to consecutive rising edges of an external signal applied to pin PA3 (which is Timer2 Channel4 input).The Input Capture in...
